Not to trash the hard work that was put into Icarus Verilog. Its hard enough trying to track down my own bugs, let alone somebody elses. Some things are worth paying for a *team* of engineers to do. That being said, having free tools are nice. But this is a non-issue now. I think just about all of the major vendors give away versions that are tools that will cover quite large applications. I think the open source part is a non-issue. There is almost nothing that most can do to optimize the synthesis algorithms. At best, you'll match what Synplicity, etc. have already done. And if you add up the time trying to get there, its not worth it. You might as well put that same amount of time running a lemonade stand and then buy a copy of commercial synthesizer with the profits. Either way your out 4000 Man-hours, but with one latter option you'll end up with a better product and support! If you feel you can optimize a piece of HDL better, you'll just implement your design by instantiating gate level primitives! And if you are even more motivated, join the synplicity, Xilinx, etc. team! Just my thoughts... -Eli

I don't use the iverilog for synthesis - however I *do* use it for rtl simulation - since I can't find other free simulators to run on Linux - and for hobby projects (even large ones) it is quite good imho. A pity if it disappeared completely - time for making a fresh backup of the current source tree on my HDD - I'd be quite stuck without it ;) -- Brian Eli Hughes wrote:> GaLaKtIkUs� wrote: > >> Does anybody knows why does the Icarus Verilog disapeared? >> >> Mehdi >> > > > Not sure!

Hi Jan, Although I understand the usual "your mileage may vary," but recently I spent two days trying to run a PCI IP core (Xilinx LogiCORE PCI compatible BDS XPCI PCI IP core) I developed with IVI (Icarus Verilog Interactive). The binary of IVI I used was ivi-0.4-pre-20031121-setup.exe from sourceforge.net (http://sourceforge.net/project/showfiles.php?group_id=53425), the last version without Eclipse. The reason I picked IVI instead of the regular Icarus Verilog was that I have not been successful running Icarus Verilog from Windows 2000's Command Prompt, and also Icarus Verilog doesn't come with GUI. Because of the low expectations people have of free EDA tools, I honestly didn't think IVI can run BDS XPCI PCI IP core along with the simulation model of Xilinx LogiCORE PCI, but it somehow did finish the simulation. Wow, that's not bad, it beat my very low expectations. The simulation speed of IVI was okay if not great for me, but the biggest problem of IVI (and perhaps Icarus Verilog) was that the compilation and loading of the entire design was soooooo slow that it probably will make it useless for most people to use as an HDL simulator. Maybe the more recent version of Icarus Verilog might be better, but I have not been able to run IVI with Eclipse. (Took three days to figure out how to install it, and it crashes when I try to run it.)

But the nice part about GPL'd stuff is that it will always be available somewhere, if not on sourceforge. see http://www.geda.seul.org/tools/icarus/ where it's embedded in the gEDA project, and is likely to maintained there if the author has given up on it.

It's natural that the website goes down in such a situation... The other option for a free simuator is http://www.pragmatic-c.com/ I am very glad about those two option.

I'd say get it while you can, it is only 3.5GB or so...

Honestly :-) if withing 10 minutes or so I cannot figure out what exactly it does (Eclipse) and how it works and [how it] could speed up or improve the whole process, then I am out of there! IBM must have dumped it into the public domain for the same reason, and then they can claim 'millions of dollars donations to open source'..... So, you know, my sort of dream of GUI based FPGA software would be something that allowed me to drag and drop objects on a form (the FPGA), say a filter, an IO block, a Viterbi decoder, a multiplier, a FIFO, all sort of things. And then click on it and specify its parameters Make your own blocks too. Do some interconnect by drawing a line and indicating number of bits, add some processor and code perhaps, and press 'realize', and it would recommend a FPGA from some manufacturer, and generate a bitfile for it. I do not usually check object code gcc produces, I trust it.... nor use asm as output. for inspection, gcc produces output for many processors. In such a case anyways I could see the use of a GUI tool like that. Maybe a dream...
